Norfolk and Western railway's J class steam locomotives were a class of 4-8-4 locomotives built by the Norfolk and Western railway's east end shops in Roanoke, Virginia between 1941 and 1950. The first batch, numbered 600 to 604, were built in 1941-1942 and were delivered streamlined. In 1943, 605-610 were delivered without shrouding and lightweight side rods, due to these distinctions, they were classified as J1. But, when N&W showed the War Production board the reduced availability numbers because of this, the Board allowed J1's to re-fitted as J's with the lightweight rods and shrouding in 1944. The last batch, 611-613, were built in 1950, and were all streamlined. The J's were built and designed completely by N&W employees, something that was uncommon on American railroads. The class should not be confused with the much earlier J class of 1903.
